2025 Suzuki GSX-8S

Body & Styling Features

• The GSX-8S fulfills the goal of creating a thoroughly modern design that sets a trend for the next generation of exciting Suzuki motorcycles ready to carry the brand into the future.
• The 2025 GSX-8S offers two body color choices: Glass Sparkle Black / Pearl Cosmic Blue (CLB) or Metallic Matte Black No. 2 (YKV)
• The GSX-8S adopts the graphic and font motif that first appeared on the 2022 GSX-S1000. This not only connects this model to the S1000’s naked roadster legacy, but further emphasizes the “8S” moniker which resembles the endless loop of the infinity symbol.
• Diligence extends to the engine as the clutch cover and magneto cover have dark-gray finishes that complement the GSX-8S body colors, while the SUZUKI name on the cover is in a contrasting silver to bring attention to this modern engine.

Chassis Features

• Designed around the compact parallel-twin engine and constructed with rugged steel pipe, the GSX-8S’s backbone style frame was developed to provide excellent straight-line performance, to contribute to nimble handling, and to perform well in the city, on twisty roads, and at highway speeds.
• The GSX-8S rides on 17-inch lightweight, cast aluminum wheels that look great and contribute to the bike’s nimble handling and sporty performance. Dual front brakes with 310mm diameter discs and radially mounted NISSIN four-piston calipers provide strong and consistent stopping power and a 240mm stainless-steel rear disc brake with a NISSIN single-piston caliper to help ensure controlled stops. Both the front and rear brakes can be modulated by a compact Anti-lock Brake System (ABS)** controller to match stopping force to the available traction.
• The steel sub-frame has short and narrow seat rails that result in low and slim seating that helps riders maneuver the motorcycle and touch the ground at stops.
• Matched to the GSX-8S’s chassis geometry and suspension is a uniquely shaped aluminum swingarm that enhances vertical, lateral, and torsional rigidity to aid straight-line stability and controlled cornering.
• The 3.7-gallon (14L) fuel tank has a narrow rear section that flows into the front of the rider’s seat, creating additional clearance for the rider’s knees.
• The GSX-8S features a wheelbase that is longer than a typical naked street fighter, and this contributes to straight-line stability. Even so, the chassis geometry was adjusted to ensure nimble handling and cornering ability by maintaining an upright riding position.

Electrical Features

• The advanced electronic systems of the Suzuki Intelligent Ride System (S.I.R.S.) let GSX-8S riders optimize performance characteristics to best suit their riding style, level of experience, and riding conditions. The GSX-8S instrument panel uses a full-color, 5-inch TFT LCD screen to give the rider information on these systems and their current settings.
• Suzuki Drive Mode Selector (S-DMS) provides the rider with a choice of three different engine power output modes. These three modes (A, B, and C) provide the rider a quick and effortless way to alter the GSX-8S’s power delivery characteristics to match his or her riding style or adjust to changing weather, road surface, or other conditions.
• The four-mode STCS on the GSX-8S lets the rider control the throttle with more confidence by limiting rear wheel spin in a variety of riding conditions.
• The electronic throttle system uses the capability of the GSX-8S’s 32-bit, dual-processor ECM, and CAN-bus wire harness to convert throttle grip movement and sensor input into instantaneous and precise throttle plate movement in the two 42mm throttle bodies.
• Equipped with a Bi-directional Quick Shift system, the GSX-8S allows the rider to shift up or down quickly, easily, and smoothly, without operating the clutch or throttle. The Suzuki Easy Start System allows the rider to easily start the engine with a single button press. And the Low RPM Assist system seamlessly increases engine speed to smooth the power delivery when launching or riding at low speeds.
• The handlebar switches are designed for intuitive operation (so the rider can better maintain focus on the road). And the LED headlights, position lights, turn signals, and taillight complement the GSX-8S’s sharp, angular styling while improving both visibility and durability.

Engine Features

• The new-generation 776cc parallel-twin DOHC engine delivers a superb balance of smooth controllable torque-rich power from low RPM and freely revs up to its peak power output with a 270-degree crankshaft configuration provides a similar, but more powerful experience as provided by the 90-degree V-twin engine used in the SV650 models.
• Suzuki Cross Balancer technology, patented by Suzuki and used for the first time on a production motorcycle, helps create a compact, lightweight design that delivers smooth operation. The spaced nature of the engine’s power pulses enhances the maneuverability of the GSX-8S in slow traffic and tight corners.
• The 84mm cylinder bores inside the aluminum die-cast cylinders are plated using Suzuki’s SCEM process. Dual, 10-hole, long-nose, linked 42mm electronic throttle bodies use a configured Accelerator Position Sensor (APS) to provide an authentic response and feel to the rider’s throttle operation.
• The 6.0L air cleaner box shape and intake pipe lengths were created using computer-aided design to help maximize peak power output plus strong torque production at low engine speed. The air box size and shape contribute to the GSX-8S’s slim chassis.
• Most of the exhaust system is located under the chassis in an optimal, centralized location that benefits handling. The stainless-steel 2-into-1 exhaust system uses a high flow, dual-stage catalytic converter inside the mid-pipe and a short muffler design with an upswept end cap that slightly protrudes from the right side of the chassis producing a unique exhaust note.
• The digital ignition fires iridium-type spark plugs that increase spark strength and combustion efficiency and a unique cooling system inlet control thermostat valve helps maintain consistent engine temperature and smooths the idle speed during warm-up.

Key Features

• PARALLEL-TWIN ENGINE: SMOOTH OPERATION - compact 776cc parallel-twin engine uses a 270-degree firing order for strong torque production and is equipped with Suzuki’s exclusive Cross Balancer system for smooth operation.
• QUICK SHIFTER: CLUTCHLESS SHIFTING - The Suzuki Clutch Assist System (SCAS) smooths shifting and engine braking, while shifting has never been easier with the Bi-directional Quick Shift system.
• SUZUKI INTELLIGENT RIDE SYSTEM: ADVANCED RIDER AIDS - The GSX-8S uses the Suzuki Intelligent Ride System (S.I.R.S.) with a three-mode Suzuki Drive Mode Selector and the four-mode Advanced Traction Control System* plus the popular Easy Start & Low RPM Assist systems.
• ANTI-LOCK BRAKE SYSTEM: Stopping power - ABS-equipped** NISSIN radial-mounted 4-piston brake calipers with dual, floating brake rotors provide controlled stopping power.
• X: TURN HEADS ANYWHERE - Thoroughly modern streetfighter design that sets a trend for an exciting new generation of Suzuki motorcycles ready to carry the brand into the future.

Transmission Features

• The six-speed transmission features gear ratios that deliver exciting acceleration, whether shifting normally or when using the standard-equipment Bi-directional Quick Shift system to shift without clutch operation.
• The GSX-8S’s precise shift linkage helps the rider easily and quickly select the ideal gear for the riding conditions. A sensor on the shift rod sends shifter movement data to the ECM, so the Bi-directional Quick Shift system precisely responds to the rider’s actions.
• The transmission’s output is managed by the Suzuki Clutch Assist System (SCAS). This large-diameter, wet, multi-plate clutch uses a precise cable-activated release, providing the rider with a light pull that also has superb friction-point feel.
• A programmable shift light on the main panel provides a visual alert to the rider to shift when a certain engine rpm is reached.
